I ordered a capacitive discharge (CD) stud welder for an upcoming sheet metal project for a client. I went with
this unit from Hanlon Stud Welding. Made in the USA and already proving to be a great company to work with.
I ordered a box of 500 of the non-flanged in preparation for the project. My thinking was the flange would require a larger hole in the base panel. Flanged on the left, non-flanged on the right:
Whelp.. the flanged weld like ****. I shot about 50 of them, talked to the company I bought from twice, and yielded two good welds out of the 50, after a ton of adjusting and tinkering.
As part of the process, I tried a couple of the flanged that came in a starter kit with the welder. The worked GREAT! The destructive test is what they recommend.. either bend over until it breaks or by running a nut down until failure. The flanged studs in all sizes bend over and break leaving the weld in place. I was only able to get one or two of the non-flanged to pass the destructive test. I'll probably continue to play with them as I get more acquainted with the process.
Turns out Hanlon doesn't recommend or even use the non-flanged much at all. The effective size of the stud is much smaller, so the presets don't apply for these, etc.
SO.. I ordered quite the assortment of flanged in 6-32, 8-32, 10-24, and 1/4-20. There's a lot of application for stuff like this and it's a cool addition to the shop. The assortment will be great for trying out ideas, prototypes, etc. Then order in quantity for a specific product or project. This is how I do fasteners and other materials in general. It's nice to have enough on hand for one offs and product development.
Speaking of products.. continuing to work on the tooling kit order. The next part is perfect for running two at a time in OP1 and OP2. Great opportunity to learn some more advanced and efficient methods in Fusion. The part is only drawn once, and the toolpaths are only made once. Both are then in a circular pattern around that black line poking up in the middle. Working with the consultant is really working out well and very much worth the cost!
